Microsoft Download Center blocking Deer Park users

It worked fine when I pretended to be MSIE, and it worked fine when I set it to Opera. It worked with Firefox 1.0. I eventually worked out that the Microsoft script is failing on the Gecko version of "1.8b2". Remove the "b", and it works.

A bit pathetic that the script crashes out if the User-Agent isn't exactly as expected, but meh, at least it doesn't seem to be intentional.
